Did you know? Stars form in dense clouds of the interstellar medium, but even in these densest regions the pressure is comparable to the most tenuous vacuum created in a laboratory on Earth. In these clouds, the temperatures are below -200 degrees Celsius.

Did you know?The skies over the ESO sites in Chile are so dark that on a clear moonless night it is possible to see your shadow cast by the light of the Milky Way alone.

Did you know?There is an Earth-mass of alcohol near the centre of our Milky Way. However, most of it is methanol, and it is diluted 1:1000 with water. Telescopes observing at millimetre and submillimetre wavelengths, like APEX and soon ALMA, are used to detect many other molecules in space.
